After you have a box full of worthless judgements and get tired of trying to have them served in the first place, consider turning them over to a collection department. Yes, you'll probably never get much but at least you can put it on their credit & possibly, someday get paid. I can't spend ½ a day at the Hall of Injustice for a deadbeat that probably won't pay & a judge that will cut my claim down. So I let it go in my mind & turn them over to collections if it's significant enough to me. Clean & simple.
This is what I did when working for large property management company.
At final walk through (with or without tenant there), I would document and photograph any damages that I planned to charge for, put them in a ledger back in my office, print it out, and mail it immediately to the tenant's forwarding address. If a refund was due, I included a note that my accounting team would cut a check on X date, so they could expect it a few days after that. If a balance was owed, I'd include a due date with a note that said that they could pay by that date, set up a payment plan with me by that date, or I would send to collections.
I had some folks paying $50/month on old damaged apartments, but at least it didn't hit their credit, and I still got some money.
If it got to the point where I didn't hear from someone by the due date, I'd call them and send an email if they didn't pick up, advising them that I'd be sending them to collections by the end of the day if I didn't hear back.
With collections, I got a portion of the money back, or nothing, but there was no downside to me. I was either writing the money off or getting something.
